How to mix sodium silicate solution with sodium hydroxide solution...

Dear Rajitha, unfortunately I'm not a proven specialist in this field of research as we are working in synthetic inorganic chemistry. Thus I cannot really give a qualified expert answer. All I can do right now is suggest to you a few potentially useful literature references. Please have a look at the following articles:
EFFECT OF SODIUM SILICATE TO SODIUM HYDROXIDE RATIOS ON DURABILITY OF GEOPOLYMER MORTARS CONTAINING NATURAL AND ARTIFICIAL POZZOLANS
This paper is freely available as public full text on the internet (see attachment).
Also please check:
The effects of the sequential addition of synthesis parameters on the performance of alkali activated fly ash mortar

and
Effect of sodium hydroxide and sodium silicate solution on compressive strength of metakaolin and GGBS geopolymer
Article Effect of sodium hydroxide and sodium silicate solution on c...

Both papers have been posted by the authors as public full texts on RG, so that you can freely download them as pdf files. I hope these links contain some useful information for you. Good luck with your work and best wishes, Frank Edelmann

1. Fix the ratio of Sodium hydroxide solution (SH) to Sodium Silicate Solution (SS) as per grade of GPC.
2 . After fixing the ratio SH/SS, for example let say SH/ SS =2.5
Now consider 100 gm of binder , binder to alkaline ratio is 0.35 ( assume)
3. For 100 gm of binder add 35 ml of solution which consists of 10 ml of SH and 25 ml of SS
4. Prepare the alkaline solution just before 1 hour of casting
5. Mix together SH and SS as per proportion just before 1 hour

It is necessary to prepare liquid glass with a density of 1.4 g / cm3 with a volume of 4 liters. Next, an alkaline solution of sodium hydroxide with a density of 1.1 g / cm3 with a volume of 1 liter is prepared separately. In this case, you need to be more careful, since when sodium hydroxide dissolves, a large amount of heat is released, as well as a gas that irritates the respiratory tract, skin and closing eyes. Then these two mixtures are mixed with each other and left for 1 day. After the prepared mixture is diluted with water to the desired density. Also, it is necessary to take into account the silicate module of the liquid glass.

Not sure why one would add NaOH to GPC as the cement is already alkalian from the lime. Sodium Silicate (water glass) is used as a surface sealant. One can buy it all ready made up for direct placement but it can be watered down for a quick seal application before painting. Read the instructions.
